"Mr. Dubinsky was professional from the very start! He did a great job of explaining when I had questions and relieved and concerns I had about the job. We had put off having flooring installed because a good portion of it was ceramic tile and glued linoleum. We imagined it taking days to demolish all of the floors. I couldn’t believe it when his crew completed that back breaking work in one day! We were very impressed with how precise his crew installed our Pergola flooring and baseboards. Absolutely flawless!"

"We shopped around and found the flooring that we liked. The representative (very nice gentlemen) came out and measured the area and provided the estimate. The vinyl had to be ordered since none was available and Armstrong had to manufacture (in Georgia). This would take 30 days but we were willing to wait. There was no additional charge for this. Approximately 3 weeks after ordering, we were called and set an appointment. The installers arrived on time and within 4 to 5 hours, the work was completed beautifully."

"Juan did a complete remodel of one of our baths. It was a half bath and now we added a shower. He was professional, on time, and kept us up to date on the progress. He communicated clearly and if there were any changes along the way he made sure we were aware of what needed to be done and why. He did an excellent job and turned a dull old bath into a sleek/modern luxury bath. The space was small so he helped me realize my vision of what I wanted the bathroom to be. It is now my favorite bathroom in the house. I highly recommend Juan! I will definitely be working with him in future home projects. Thank you!"

FAQs for attic insulation installation projects in San Lorenzo, CA

The best attic insulation depends on where you live, the project stage, and your budget. New builds often benefit from structural insulated panels for top-tier efficiency, while homes in very warm regions can see big cooling savings with reflective insulation. Blown-in, loose-fill, and spray foam all excel at filling odd spaces in finished attics. Talk with a certified local pro to match the material to your climate, space, and wallet.

You’ll only need a licensed electrician if the project calls for moving existing wiring or adding new fixtures. For straightforward insulation jobs, your insulation installer can work around current cables. That said, never start insulating until a pro has checked any questionable wiring. If you suspect damaged or outdated circuits, book an electrician first to keep the project—and your home—safe and code-compliant.

Without air sealing, even the best insulation can underperform. Gaps let heated or cooled air leak out, forcing your HVAC system to work harder and driving up energy bills. Sealing those cracks before adding insulation locks in conditioned air, keeps moisture at bay, and helps the new material hit its full R-value. Ask your insulation pro to tackle sealing first so you enjoy consistent comfort and lower monthly costs.

Among readily available options, structural insulated panels and rigid foam boards top the charts with R-values that can reach 8.0. They’re ideal for new construction or very cold climates where maximum thermal resistance matters most. If you live in a milder zone, blown-in or loose-fill insulation may deliver plenty of performance at a lower price. Weigh the upfront cost against energy savings—and lean on a local pro’s guidance—to pick the smartest fit.
